Finding effectively relevant information is becoming challenging task. In this paper, we propose a smart information filtering system SIM-Filter that integrates user’s identity and preferences data modeled in his profile. User profile is embarked in a smartcard in order to guarantee its privacy, confidentiality, and mobility. SIM -Filter objectives are twofold. First, we propose a secured, evolved and extensible model to represent user’s preferences. Second, our system must provide pertinent information to user according to his profile at any time, anywhere, and in any form. KEYWORDS Information filtering, user profile, security, mobility, smartcard.
